Study on objective evaluation method of taxi driver safety consciousness

This study aims to conduct researches on the correlation between driver safety consciousness and several indices, and propose an objective evaluation criterion, which can covert immeasurable safety consciousness to measurable objective indices. A number of taxi drivers were selected as study subjects, and their safety consciousness was evaluated by using fuzzy comprehensive evaluation method. Combined with the number of accidents these drivers involve in a year, the correlation between driver safety consciousness and accident numbers was investigated. And combined with GPS surveillance data, the correlation between driver safety consciousness and the mean speed, speed dispersion, and max vehicle speed was analyzed. Then the identification model between max vehicle speed and driver safety consciousness level was established. The results show that driver safety consciousness level is correlated with accident numbers, and not correlated with the mean speed, correlated with vehicle speed dispersion, and highly correlated with max vehicle speed. According to fuzzy identification model, max vehicle speed obtained from statistics circle can be used to evaluate and categorize driver safety consciousness. Verification shows that the driver safety consciousness evaluation model, which based on the max vehicle speed, is effective. It can overcome the demerits of scale evaluation, effectively identify driver safety consciousness level, and provide guidance for driver safety education, management and training.
